START_PVMD(3PVM)		 PVM Version 3.4		START_PVMD(3PVM)

NAME
     pvm_start_pvmd - Starts new PVM daemon.

SYNOPSIS
     C	  int info = pvm_start_pvmd( int argc, char **argv, int block )

     Fortran   call pvmfstartpvmd( args, block, info )

PARAMETERS
     argc    Number of arguments in argv.

     argv    An array of arguments to the executable.

     args    A character string containing the arguments to the executable.

     args    A character string containing the arguments to the executable.

     block   Integer specifying whether to block until startup of all hosts com-
	     plete or return immediately.

     info    Integer returning the error code.

DESCRIPTION
     The  routine  pvm_start_pvmd starts up a pvmd3 process, the master of a new
     virtual machine.  It returns as soon as the pvmd is started and  ready  for
     work.   If  the  block parameter is nonzero and a hostfile is passed to the
     pvmd as a parameter, it returns when all hosts marked to  start  have  been
     added.  pvm_start_pvmd returns zero on success.

     If  PVM  is  compiled  to allow running more than one pvmd per host, a task
     calling pvm_start_pvmd before any other pvm functions will connect  to  the
     pvmd  that  it starts.  pvm_start_pvmd sets environment variable PVMSOCK to
     the address printed by the pvmd as it starts up.

EXAMPLES
     C:
	  static char *argv[] = {
	      "-d41",
	      "/u/jones/pvmd_hosts",
	  };
	  argc = 2
	  info = pvm_start_pvmd( argc, argv, block );

     Fortran:
	  CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )

EXAMPLES
     C:
	  static char *argv[] = {
	      "-d41",
	      "/u/jones/pvmd_hosts",
	  };
	  argc = 2
	  info = pvm_start_pvmd( argc, argv, block );

     Fortran:
	  CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )

ERRORS
     The following error conditions can be returned

     PvmDupHost
	    A pvmd is already running.

     PvmSysErr
